Plankton recognition using similarity learning
(2021)
Several automated classification methods for plankton images have been developed. These methods typically require an explicit description of features, data augmentation, and are not suitable for classes with a few example ...
Smart grasping of known objects
(2020)
Smart grasping means that a robot can automatically decide which object and how an object can be grasped. Firstly, a neural network should find the objects and get a 2D bounding box. The convolution neural network is used ...
Image clustering for unsupervised analysis of plankton data
(2020)
Advancements in automated imaging has made it possible to enhance the data both in terms of quantity and quality. This has prompted the development of plankton imaging systems for acquiring the species level information ...
3D reconstruction of logs from board images
(2022)
Sawmills nowadays are heavily automated and especially sawing process optimisation could improve overall yield of sawn timber. The main focus of this thesis work is to create a method to reconstruct a 3D-model of a log ...
Determination of resolution, repeatability, and detection capability improvements of automatic optical inspection in micro-electro-mechanical systems manufacturing
(2022)
Automatic optical inspection (AOI) is a quality monitoring system used in many industries. In semiconductor industry, it is used to detect anomalies, inter alia, defects in wafers and micro-electro-mechanical systems (MEMS). ...
Active learning for plankton recognition
(2022)
Plankton is essential part of the ocean ecosystem as it is an important food source for many marine life, both large and small and is also oxygen producer. Therefore, its quantity and condition must be monitored and its ...
Geometric verification for Saimaa ringed seal re-identification
(2023)
Ongoing conservation efforts of the Saimaa ringed seal (Pusa hispida saimensis) utilize an image-based re-identification, but the re-identification is mostly done manually. Due to enlarging image data sets of seals, the ...
Real estate building detail enrichment with street view image prediction
(2024)
Within the domain of urban analytics, fundamental aspects defining a real estate property include its construction year, number of floors, and building use. However, it is essential to acknowledge that obtaining accurate ...
Face anti-spoofing by using diffusion model
(2024)
This thesis explores the potential of diffusion models for improving face anti-spoofing (FAS) techniques. Due to the increasing usage of facial recognition systems in various domains, such as smartphone unlocking, airport ...
